Run the numbers
What gravimetric control pays back in a year
The manual says it saves 2%–5% of raw material. Three numbers will tell you what that sentence is worth on your line.
At 2% (conservative)
— CNY / year
— tonnes / year
At 5%
— CNY / year
— tonnes / year
Have an engineer run it on my line
Basis: Sealion Product Manual, Gravimetric Control System — Main function: "Solve the problem of meter weight deviation and waste material — can save 2%–5% raw material." This is arithmetic only; it excludes savings from start-up scrap, material changeover and screen-pack blockage. Real figures depend on your line — ask an engineer to run it properly.
Have an engineer run it against your line
Those three numbers are arithmetic. What you actually save depends on formulation, diameter, scrap rate and changeover frequency — tell us about the line and we will work it out on site.
